A growing body of evidence has begun to reveal flaws in the traditional assumption of female passivity and lack of discrimination after copulation has begun. William Eberhard has compiled an impressive array of research on the ability of females to shape the outcome of mating. He describes studies of many different cryptic mechanisms by which a female can accept a male for copulation but nevertheless reject him as a father. Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most post-copulatory competition between males for paternity is played out within the bodies of females, female behavior, morphology, and physiology probably often influence male success in these contests. Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans. Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating. Eberhard interweaves his review of previous studies with speculation on the consequences of this theoretical development, and indicates promising new directions for future research.

"In this pithy two-part essay, Marshall Sahlins reinvigorates the debates on what constitutes kinship, building on some of the best scholarship in the field to produce an original outlook on the deepest bond humans can have. Covering thinkers from Aristotle and Lévy- Bruhl to Émile Durkheim and David Schneider, and communities from the Maori and the English to the Korowai of New Guinea, he draws on a breadth of theory and a range of ethnographic examples to form an acute definition of kinship, what he calls the "mutuality of being." Kinfolk are persons who are parts of one another to the extent that what happens to one is felt by the other. Meaningfully and emotionally, relatives live each other's lives and die each other's deaths. In the second part of his essay, Sahlins shows that mutuality of being is a symbolic notion of belonging, not a biological connection by "blood." Quite apart from relations of birth, people may become kin in ways ranging from sharing the same name or the same food to helping each other survive the perils of the high seas. In a groundbreaking argument, he demonstrates that even where kinship is reckoned from births, it is because the wider kindred or the clan ancestors are already involved in procreation, so that the notion of birth is meaningfully dependent on kinship rather than kinship on birth. By formulating this reversal, Sahlins identifies what kinship truly is: not nature, but culture."--Publisher's website.

Fortpflanzung als das ›natürlichste‹ Phänomen der Welt wird häufig als Begründung für die Geschlechterdifferenz herangezogen und dient als Rechtfertigung für das hierarchisch strukturierte Geschlechterverhältnis. Auf der Grundlage der Soziologie Pierre Bourdieus fragt Daniela Heitzmann, wie sich jene vermeintliche Naturtatsache als soziales Phänomen begreifen lässt, um dessen enge Verknüpfung mit dem Frausein einerseits und das eher lose Verhältnis zum Mannsein andererseits zu analysieren. Hierzu entwickelt sie ein Konzept der generativen Praxis, das zu einem Forschungsprogramm zur Genese von Generativitätsvorstellungen führt und dabei besonders die soziale Konstruktionsarbeit der Soziologie in den Fokus rückt. »Der zentrale Anspruch und sicherlich auch die besondere Leistung von Heitzmann ist es, das große Potential der soziologischen Perspektive Bourdieus für die Geschlechtersoziologie aufzuzeigen. Eindrucksvoll ist bei dieser Publikation im Besonderen die breite Rezeption sehr unterschiedlicher empirischer Studien, die zum Zwecke der Theoriebildung systematisiert und reinterpretiert werden.« Karl Lenz, Soziologische Revue, 40/4 (2017) »Eine kritische, wichtige, verwirrende und sehr weitgreifende Beschreibung der sozialen Kategorie ›Frau‹, die von so vielen Ebenen bespielt, eingeschränkt und geformt wird.« WeiberDiwan, Sommer 2017 Besprochen in: Gen-ethischer Informationsdienst, 245 (2018)

Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.
